This paper reviews technological options for the modulation formats for serial optical
transmission of 100Gb/s and beyond. In the first part an overview on various modulation …

Power consumption and the footprint of future network elements are expected to become the
main limiting factors for scaling the current architectures and approaches to capacities of …

Most of the digital data transmitted are carried by optical fibres, forming the great part of the
national and international communication infrastructure. The information-carrying capacity of …

Focus Issue on Orthogonal-Frequency-Division Multiplexed Communications Systems and
Networks We discuss the realization and performance of polarization-division-multiplexed …

Digital signal processing has completely changed the way optical communication systems
work during recent years. In combination with coherent demodulation, it enables …

This article proposes an optical parametric amplifier (OPA), as an inline-repeater, using a
periodically-poled-LiNbO_3 (PPLN) waveguide with over-10-THz amplification bandwidth …

The optical parametric amplifier (OPA) has attractive features for optical communications,
such as a wideband, high gain, and fast transient response. In addition, by using idler light …

The 25 years since the founding of the Journal of Lightwave Technology have seen more
than three orders of magnitude increase in the capacity of optical transmission systems. This …

We experimentally demonstrate 101.7-Tb/s transmission over 355 km spans of standard
single-mode fiber (SSMF) at a net spectral efficiency of 11 b/s/Hz. A total of 370 dense …
